Just had a big temp swing on Lake Huron with winds shifting out of the north. Saw this on radar and was wondering if anyone could explain it. Is it low level precipitation created along the wind shift?
I grew up thinking ceiling fans in the summer should pull air up because that's where the cold air is, and should push air down in the winter because that's where the warm air is.
Every recommendation I've seen says the opposite, but most are vague about the real mechanics of redistributing the different air masses. For example, a lot focus on the cooling effect of having air blowing down on you in the summer, which is true, but a human factor.
I'm interested in a more technical analysis of this, is anyone aware of a good deep dive into this? Explanations I've seen still sound like vague hearsay and hand waving.
